We stay at Rush-no-more. Its a yr round campground with nice crappers and showers. A pool and hot tub. I think its $10 a day, non rally time. Its all paved. Exit 36 or 38. There is only campgrounds at that exit. There is a KOA on the west side of Deadwood. Never been to it but it looks like a nice steep ride up to it! Spearfish has a neat looking one to, chris's camp ground I think. Valk rider here stays there. In Deadwood if you goto Mt Morhia to Hickoks grave, watch when parking. Its a steep angle that is hard to see. Bikes get dropped all the time.
www.rushnomore.comCuster wildlife loop, Needles, Iron MNT Rd, Rushmore, crazy horse can all be done in one good day. Deadwood and Spearfish canyon are a must. Vanocker Canyon is a nice quiet rd. Exit 32. It winds to the west of Rapid, or there is a side road that will take you into Needle/rushmore area. Not sure the name of it but its hard to find. Stop in Alladin WY since you will go by it. Cheap drinks. Stone House saloon is between Alladin & Belle Fourche, if its open. Cont east into Belle Fourche and take the road thru St Onge to Sturgis. 212 I think. Bear Butte Mnt is kinda neat. East of Sturgis. You cant miss it. You can see it from the I/S from between Spearfish & Sturgis. Its a State park so go to custer/needles first then to BB. That way your Custer pass will get you into Bear Butte. Or you will pay twice.
Stop and get a map. Rest stops have them and so do most bussinesses.
